7 Claims.

My invention relates to a bearing and particularly to means for mounting an anti-friction bearing.

It is an object of my invention to provide a mounting for an anti-friction hearing which will to a large extent eliminate bearing noise.

It is a further object to provide a bearing housing of sound deadening material which will facilitate the assembly of the bearing with the housing.

Another object is to provide a bearing housing of sound deadening material, which is simple tomanufacture, effective in use, and easy to apply.

Other objects and features of the invention will be hereinafter pointed out or will become apparent to those skilled in the art.

In the drawing which shows, for illustrative purposes only, preferred forms of the invention- Fig. 1 is an axial view of a bearing and housing applied to a frame member or support;

Fig. 2 is a sectional view taken substantially in the plane of the line 2-2 of Fig. 1;

Fig. 3 is a top plan view of the parts shown in Fig. 1;

Fig. 4 is an axial view of a modified form of bearing support or housing, with a bearing and shaft in place;

Fig. 5 is a top plan view, partly broken away, of the parts shown in Fig. 4 applied to a frame member or support.

In said drawing, 6 indicates a supporting member, which may be a framework or other part of a machine or the like which is to support a bearing. The bearing in the preferred form shown comprises an outer bearing ring I and an inner bearing ring 8 with interposed anti-friction bearing members such as balls 9. The bearing is preferably sealed at opposite sides by means of seal plates I ll, as will be understood. A shaft II is carried by the inner'r'ing and as illustrated is shouldered so as to engage one edge of the bearing ring, and any suitable means such as a fixed collar or the like may secure the bearing against movement on the shaft in the other direction.

The housing for the bearing, in the form shown a in Figs. 1 to 3, comprises a housing of sound deadening material preferably formed so as to provide a base plate and upstanding housing portions for engaging parts of the outer bearing ring. As illustrated I have provided a base plate l2 of sound deadening material, preferably rubber, to fit fiatwise against the face ofthe frame 6, as shown particularly in Figs. 2 and 3. The base when designed for a through shaft has an axial opening or bore I3 concentric with the bearing and preferably larger than the shaft passing therethrough. A pair of bearing housings I i-I4 extend up integrally from the base I2 and may be spaced apart a suitable distance as illustrated. The upstanding housing portions I l-l4 are provided with complementary arcuate surfaces l-l5 to engage the outer bearing ring circumferentially and hold the same in place. As shown in Fig. 2 the outer bearing ring is designed to be forced into the housing until the edge of the ring engages the base plate 12 at the bottom of the arcuate recess. In the form shown in Figs. 1 to 3, the outer end of the housing is open, while in the forms shown in Figs. 4 and 5 there is provided an outer flange or lip so that the outer ring is supported axially by the housing in both directions. 15 With the illustrations of Figs. 4 and 5 it will be clear that such a lip or flange could be provided in the form shown in Figs. 1 to 3, if desired.

In order to assemble the bearing with the housing the two housing members I ll4 may be moved relatively to each other by bending the base plate at the connecting portions l6l6, which movement will of course have the effect of separating the housing portions and radially enlarging the opening formed by the arcuate supporting surfaces |5-|5. When the bearing is slipped into place, the housing portions I l-I4 are either moved back or spring back to normal positions so as to securely hold the bearing. When the hearing has been assembled with the housing, the latter is applied to the support 6 and may be secured thereto as by means of the bolts I1 l1, two bolts preferably being provided for each housing part l4. These bolts, as illustrated, ex-. tend in a direction axially of the bearing and are sufficiently spaced from the bearing supporting portions so that the liveness and resiliency and sound deadening properties of the rubber at the bearing supporting parts are affected little or none.

Whether the shaft is shouldered or whether a collar or a press fit of the inner ring on the shaft is employed, it will be clear that when two bearing housings of the character illustrated are used on the shaft, the bearings may be secured on the shaft so as to slightly compress the rubber base l2 and thus always keep the bearings under some thrust or angular contact load. It is there-fore unnecessary to provide for a fixed and floating bearing, since the shaft will be held with considerable firmness against any axial movement by merely properly placing the bearings so as to maintain them under slight load and the resiliency of the rubber will take care of all axial movement due to shaft expansion and contraction.

substantially the same as ,niernber, which'may be a In the form shown in Figs. 4 and all parts are those heretofore described, except that the two housing parts l4 II are entirely separate from each other; that is to say, there is no base plate or connecting web like the web [6 shown in Figs. 1 to 3. In the form shownrin Figs. 4 and 5, the housing members l4 M are provided with channel shaped afcuate bearing receiving recesses l8-l8 so that the outer bearing ring 1 may abut axially the inturned flange I!) in the same manner that the correspond.- ing part of the base l2 was engaged by the outer ring in the form shown in Figs. 1 to 3. In addition to the inner flange I9, there may bean outer, flange 20 so that when the two housing parts are. assembled with the bearing the latter isv held against displacement in all tion and operation of the directions. .The funcforms shownzin Figs; 4 and 5 is substantially the same as fore described. 7

In order to prevent the accumulation of static charges on the shaft or parts carried thereby, Ihave provided-means for grounding the insulated parts. In the form shown a conducting strip of metal 2| extends through the rubber plate I2 and engages both the metallic supporting member 6 and the outer ring 1'. In'the form shown in Figs; 4 and '5, the grounding connection comprises a conducting strip wrapped about the edge of the inner flange i9 and which engages the outer ring j of the bearing as well as the metallic housing or support In.

While I have .disclosed'herein an improved form of housing fora bearing which will serveto very substantially eliminate or 'deaden the bearing noises, it is to be understood that further sound deadening may be required, in which case the inner ring 8 may also be separated from the shaft by means of sound deadening material, for example asdisclosed in my application, Serial'No. 97,481, filed Aug. 24, 1936;

While the invention has been described in considerable detail, it is to be understood that vari ous changes may be made within the scope of the invention and as defined in the appended claims.
